Computational Modeling and Analysis of Intake Taper Manifold of an Internal Combustion Engine

The intake manifold is a key part of an i.c engine to feed the input air. It maybe a casting or fabricated of relatively light material. The air passes through the passage and enters into cylinder, due to bent cross-section the velocity of intake air is optimum. In order to improve the velocity of air entering in to cylinder chamber, it is proposed that the helical intake manifold with different pitches and taper at exit in the place of existing manifold, due to this the swirl motion generated in the intake helical manifold leads to increase the velocity of air which is entering into cylinder such that it may help to increase the combustion efficiency of the engine.
